the bird species, especially during breeding and incubation periods, tree cutting with chainsaw should not be coincide with these sensitive periods. In case of necessity, the noise effect should be minimized by using electric powered or Li-Ion battery saws with lower noise levels.
In order to minimize the effect of the noise caused by the chainsaw, it will be safer for the chainsaw operators and other personnel working close to the perimeter to use suitable ear protection equipment. In addition, daily working hours and rest periods should be determined according to the noise levels. In this context, the standard noise exposure times specified in the regulations should be taken into consideration. Timely and correct maintenance and insulation of chainsaws will contribute to the reduction of the noise level caused by the chainsaw. In insulated chainsaws exposed metal parts are isolated from the internal metal motor components with protective insulation.
In addition, considering that the noise from chainsaw changes depending on the type of oil used for chain lubrication, it would be appropriate to evaluate alternative oil types such as vegetable oil and mineral oil to minimize noise exposure. Occupational seminars and trainings should be given to chainsaw operators on the potential impacts of noise on human health and how to prevent these impacts. Employees should undergo periodic health checks, taking precautions to prevent temporary damages from becoming permanent and applying the necessary treatments.
This study has shown that noise propagation maps will make significant contributions in determining the noise level in a study area. However, in future studies, it would be appropriate to evaluate the noise levels arising from chainsaws with different types and power sources. In addition, it will be beneficial to develop noise propagation maps of other harvesting equipment such as harvester, feller-buncher, skidder, agricultural tractor, logging truck. In addition to bird species, other wild animal species affected by anthropogenic noise propagation should be examined in future studies.
